What is C0571?
The Diagnostic Trouble Code (DTC) C0571 indicates a fault related to the Steering Angle Sensor circuit. This code usually represents issues within the vehicle's stability control system, particularly in models from manufacturers like Chevrolet and GMC produced between 2015 and 2019. When your vehicle's OBD2 system detects a malfunction in the steering angle sensor, it triggers the C0571 code, which can lead to various symptoms affecting your driving experience. Real-world implications include compromised vehicle stability, potential loss of traction control, and the illumination of warning lights on your dashboard, such as the ABS or traction control light. Neglecting the C0571 code can lead to further complications, especially in adverse driving conditions. The steering angle sensor communicates the position of the steering wheel to the vehicle's electronic control unit, allowing for optimal handling and performance. If this sensor is malfunctioning, it can affect systems like Electronic Stability Control (ESC) and Anti-lock Braking System (ABS), making timely diagnosis and repair critical for safety and vehicle performance.
System: C - Chassis (ABS, Steering, Suspension)
Symptoms
Common symptoms when C0571 is present:
- The Check Engine light remains illuminated, indicating a need for immediate diagnostics.
- The vehicle may exhibit unusual handling characteristics, such as pulling to one side during turns.
- Drivers might notice a decrease in fuel efficiency, possibly by 10-15%, due to compromised engine performance.
- The ABS warning light may come on, signaling potential issues with braking performance.
- You may experience intermittent traction control activation, leading to unexpected loss of traction in slippery conditions.
Possible Causes
Most common causes of C0571 (ordered by frequency):
- {'cause': 'Faulty steering angle sensor', 'likelihood': '60%', 'details': 'The most common cause of the C0571 code is a malfunctioning steering angle sensor, which can wear out over time or become damaged due to impacts.'}
- {'cause': 'Wiring issues', 'details': "Loose or damaged wiring can interrupt the signal sent from the steering angle sensor to the vehicle's computer, causing the code to trigger."}
- {'cause': 'Faulty control module', 'details': 'In rare cases, the issue may be related to a malfunction in the Electronic Control Module (ECM) that interprets data from the sensor.'}
- {'cause': 'Calibration needed', 'details': 'The steering angle sensor may require recalibration after repairs or component replacements to function correctly.'}
- {'cause': 'Corrosion in connectors', 'details': 'Corrosion in the electrical connectors can lead to poor connections, causing the sensor to fail to relay accurate information.'}
